    Default 技术分析技巧随机指标

    随机指标是乔治蓝恩博士所发明的,是欧美期货市场常用的一套技术分析工具,由於期货货风险性波动大,需要较短期、敏感的指标工具,因此中短期投资的技术分析也较为适用,随机指标综合了动量观念、强弱指标与移动平均线的优点。
    计算随机指标数值时,从九天周期为例,首先须找出最近九天当中曾经出现过的最高价、最低价与第九天的收盘价,然後利用这三个数字来计算第九天的未成熟随机值(rsv)
    (第9天收盘价━最近9天内最低价)
    Rsv =━━━━━━━━━━━━━━━━━━100
    (最近9天内最高价━最近9天内最低价)
    计算出未成熟随机值(rsv) 之後,再根据平滑移动平均线的方法,来计算k值与d值。
    当日k值= 2/3 前一日 K值+ 1/3 Rsv。
    当日d值= 2/3 前一日 D值+ 1/3 当日k值。
    若无前一日的k 值与d 值,可以分别用50来代入计算,在长期的平滑运算之後,起算基期不同的,都将趋於一致,并无任何差异。
    Kd线的随机观念,在实用上远比移动平均线进步很多。在技术分析的领域上,事实上可分为图形分析与移动平均线理论两个范围。
    移动平均线在习惯上,都是以收盘价来做计算依据,因而无法表现出一段行情的真正波幅。
    也就是说,当日或最近数日的最高或最低价,无法表现在移动平均线的数据上,有些专家体认到这些缺点,而另外开创出一些更进步的技术理论,将移动平均线的应用,更发挥。
    Kd线即是其中一个代表性的杰作。未成熟随机值随着九日中高低价、收盘价的变动而有所不同。如果行情是一个明显的涨势,会带动k线(快速平均值)与d线(慢速平均值)向上升。如涨势开始迟缓,则会反应到k值与d值,使k值跌破d值,此时中短期跌势确立。
    Kd线本质上是一个随机波动的观念,对於掌握中短期的行情走势非常正确。因此可说是非常实用的利器。
    1.当k 值大於d 值,显示目前是向上涨升的趋势,因此在图形上k 线向上突破d 线时,即为买进讯号。
    2.当d 值大於k 值,显示目前是向下跌落,因此在图形上k 线向下跌破d 线,即为卖出讯号。
    3.唯k 线与d 线的交叉,须在80以上,20以下,讯号才正确。
    4.背离现象:价格创新高或新低,而kd未有此现象,亦为反转的重要前兆。
